Update plugins_disabled/omnifocus.rb

2 changes:

1st - ensure that only valid characters are saved from omnifocus.  
If a completed task contains a bullet, for example, the dayone.rb 
script will fail at content.scan on line 6 with the following error:
in `scan': invalid byte sequence in US-ASCII (ArgumentError)

2nd - added the ability to show the number of completed tasks for the day in the output file.
Do not attempt to get datestamp

- This is causing an error with the version of ruby I'm using and my feed:
